Race Spec Track Only Limited Edition McLaren Senna Confirmed
McLaren has confirmed it will build the track-only Senna GTR, limited to 75 examples and priced at £1.1 million. The Senna GTR is an even more extreme version of the road-legal McLaren Senna. The development prototypes that begin testing this month will initially use modified Senna road car bodywork.
The final Senna GTR shape – shown in a new design sketch – will be based around a chassis with wider track front and rear and centre-lock wheels.
These last two elements combining to improve aero-efficiency by ‘coupling’ the wing to the airflow from the diffuser, enabling greater – and more accessible – downforce at lower speeds.
Optimised aerodynamic performance will improve cornering stability, while reduction in pitch sensitivity leads to even greater braking stability.
A pared-back interior sees all airbags removed, as well as the infotainment central screen and folding driver display found in the road car.
A new, race-style steering wheel with integrated gearshift controls replaces the road-legal component.
Air-conditioning is an exception to the rule of absolute minimalism – remaining standard-fit – and a radar-assisted, rear collision avoidance system is also standard.
In combination with the 825PS output of the 4.0-litre twin-turbocharged V8 engine – an increase of 25PS over the road-legal Senna. Torque is also increased up to 800Nm.
The Senna GTR will retain the active aerodynamics of the road-legal car which will generate 1,000kg of downforce.
Deliveries are expected to begin from September 2019 when production of the road-legal McLaren Senna is complete.
